Definitions

  • the invention relates to a heat-sensitive recording sheet with a genuine or embossed watermarks and a color former and color acceptors heat-sensitive recording layer and its use as a ticket.
  • Heat-sensitive recording sheets with authenticity-proofing security features are well known, in particular for the area of higher-value applications, for example in the case of tickets, among other things in the form of lottery tickets and tickets and, for example, office papers.
  • authenticity-proofing security features are known, genuine or embossed watermarks are particularly popular on the market, as they provide the product they work with in addition to proof of authenticity and a more valuable appearance. Heat-sensitive recording materials with spurious watermarks are therefore often unsuitable to fully satisfy the market requirements described above.
  • Such a heat-sensitive recording material is proposed, for example, in EP-A-0 844 097, according to which the recording material has, as a first security feature, a latent image printed on its reverse side, produced by means of a security ink containing a fluorescent reagent.
  • the security ink contains a water-repellent agent.
  • Heat-sensitive recording materials of the type mentioned are known for a long time.
  • DE-U-93 02105 proposes a web-shaped carrier material for a thermosensitive recording layer having a surface of high smoothness or extremely low roughness, wherein at least one true watermark is formed in the carrier material.
  • WO-A-01109435 discloses heat-sensitive recording papers with watermark as a security feature , however, as well as the above -noted document , relates to a remote prior art in that a recording paper of two laminated paper webs, one of which has a watermark, is not disclosed is still suggested.
  • a heat-sensitive recording material which has a recognition layer on its side opposite to the heat-sensitive recording layer.
  • This recognition layer has only one of the reaction components required for a color-forming reaction.
  • a desired color reaction is initiated by application of a suitable liquid containing the second component required for color formation.
  • Paper webs with a high surface-related mass insofar as they are produced according to this known principle, require high drying capacities in the paper machine or, if these are not available, can only be produced with relatively slow-moving paper machines.
  • slow-speed paper machines are disadvantageous for economic reasons.
  • a security document to be used as a credit or debit card, driver's license or also as a label in various forms of use comprises a substrate with a pressure-sensitive image-forming coating material, which is optionally only partially applied and that of a spread or laminated protective layer is covered.
  • the substrate may include a watermark and applied to another material to form a security card.
  • DE-C-37 69 999 discloses a method for producing two-day security paper with embedded security features in the form of security threads, watermarks and the like, wherein two layers are formed on a rotary screen paper machine and the security thread is placed therebetween, optionally with additional attachment of holes or watermark, wherein during paper formation or shortly afterwards by means of air or water jets, the paper is treated in such a way that a local fiber displacement up to the formation of holes or watermarks is achieved. Subsequently, the combined paper layers are gummed together and dried. Since the document does not disclose heat-sensitive recording layers, the problem of shadows is not addressed.
  • the decolorizing layer C which at the same time is activated at these higher temperatures, causes a printed image to be prevented in coating D.
  • the cover layer B causes the printed image of the coating A does not shine through the coatings C and D.
  • secret information such as account passwords are developed only on the coating A using the higher temperature and are not reflected on the coating D. In order to make the information available to the addressed customer, the latter must separate the two release layers, one layer consisting of the base substrate with coating A, the second layer consisting of coatings B, C and D.
  • a watermark is disclosed as part of a general reference that is introduced into the base substrate.
  • the already discussed disadvantages of possible shadow images apply, so that even this document does not contain any indications as to how the object underlying the present invention is to be solved.
  • a security ticket formed as a laminate which consists of a carrier sheet consisting of paper material and of a heat-sensitive recording paper which is laminated to the carrier sheet.
  • the heat-sensitive recording paper forms the front sheet and should have sufficient transparency for a security pattern or watermark to be visible on the carrier sheet.
  • the security feature arranged on the carrier sheet is a watermark in the form of a machine-readable bar code.
  • information applied to the carrier sheet is machine readable through the transparent or semi-transparent front sheet, with watermarks incorporated in the carrier sheet or security codes printed on the carrier sheet being considered equivalent.
  • WO93 / 08992 A1 the essential teaching of WO93 / 08992 A1 is to use a front sheet of such transparency, which allows not only to recognize information mounted on the carrier sheet through the front sheet, but also to be able to decipher machine-readable barcodes.
  • the new thermosensitive recording sheet is intended to overcome the disadvantages listed above.
  • the new thermosensitive recording sheet is to have next to a genuine or embossed watermark further authenticity-proofing security features, the choice of any restrictive limits, for example by unwanted chemical reactions of the authenticity-detecting security features making up reagents with the color-forming components of the heat-sensitive recording layer must be considered.
  • thermosensitive recording sheet with a genuine or embossed watermark into which security threads may be incorporated so as to be distinctive of other thermosensitive recording materials lacking these security threads.
  • the new heat-sensitive recording sheet must be excellent as a ticket. Associated with this is the task that the new recording sheet on the side opposite to the side with the heat-sensitive recording layer must be printable by offset printing. In a preferred embodiment, the page with the heat-sensitive recording layer should be designed devaluable.
  • a heat-sensitive recording sheet has a good Entwertraj in the sense of this invention, if one of coloring pigments, not solvent-based sealer ink immediately after printing neither dry nor wet completely away from the recording sheet.
  • the application of a genuine watermark produced by displacement (so-called light watermark) or by accumulation (so-called shadow watermark) of the pulp, for example using a doffer in the wire section of a paper machine, is also a preferred embodiment for the new heat-sensitive recording sheets such as the application of a half-right, so-called Moletten watermark, which is produced by the embossing of the still wet paper in the press section of a paper machine. Since a real watermark is even more difficult to imitate than a Moletten watermark, the recording sheet according to the invention in its embodiment with real watermark then offers, if a very unique authentication proof is desired.
  • both genuine and Moletten watermarks are to be considered in the incident or incident light as well as in the backlight. If a viewing possibility is to be given in the backlight, the real watermark is more appropriate than the Moletten watermark due to slightly more distinct structures, but it is necessary for the recording sheet according to the invention to be translucent, thus limiting its basis weight to 350 g / l. m 2 and preferably to 280 g / m 2 is appropriate. If the watermark is to be recognizable primarily or exclusively in the incident or incident light, any restriction with regard to the basis weight of the recording sheet according to the invention is dispensed with. In this case, the Moletten watermark is particularly suitable as well as the real watermark, the latter, if paper is used as a substrate of the first sheet material with increased surface-related mass, preferably above 100 g / m 2 .
  • the substrate of the second web-shaped material may be formed, for example, but not limited to, from a transparent film, in particular from a film based on polyester or else from a multilayer polyolefin film. There are no limits with regard to the thickness of the film. Other materials may also be used as the substrate of the second sheet material. However, if it is to be possible to observe the watermark formed in the substrate of the first sheet-like material as it passes through the recording sheet according to the invention, it is necessary for the materials used as the substrate of the second sheet-like material to have sufficient light transmissivity.
  • the substrate of the second web-like material is formed from paper, in particular from wood-free paper having a pigment content of not more than 15% by weight and preferably with a pigment content in a range from 2 to 10% by weight ,
  • the formation of a basis weight of the paper of the second sheet material in a range of 40 to 200 g / m 2 and especially between 50 and 100 g / m 2 is preferred.
  • wood-free paper is preferred.
  • the paper is preferably in the range of 50 to 200 g / m 2 as a commercial, preferably sized and uncoated printing paper with a basis weight, and when viewed from the watermark preferably in transmitted light, particularly between 55 and 100 g / m 2 . If, on the other hand, it is preferred to observe the watermark in incident or incident light, the area-related mass should be selected in particular above 100 g / m 2 . It may be acted upon on the side facing away from the second sheet material side with one or more coatings or preparations.
  • Lt. Handbook of paper and board production (1971) are referred to as laminate laminates, which are glued together from two or more layers of paper, metal or plastic films.
  • the lamination of the first web-like material with the second web-shaped material and optionally with the other webs of material is carried out using a water-based or solvent-based adhesive, which is applied punctiform or preferably over the entire surface.
  • a water-based or solvent-based adhesive which is applied punctiform or preferably over the entire surface.
  • there is no limitation on the type of lamination and the adhesive used therefor which may also be pressure-sensitive, for example, insofar as they harmonize with the materials to be bonded.
  • a very particularly preferred embodiment provides to provide the adhesive with security features, such as colored or fluorescent fibers, metal threads, magnetic or magnetizable components or pigments, and / or perform this adhesive colored.
  • the thermal head initiating the color-forming reaction of the color formers with the color acceptors in the heat-sensitive recording layer causes the waxy constituents in the recording layer to melt.
  • an intermediate layer containing an oil-absorbing pigment or a pigment mixture is formed between the substrate of the second sheet material and the heat-sensitive recording layer, the pigments of this intermediate layer causing absorption of the melt. It is particularly advantageous if the pigment of the intermediate layer of at least 80 cm3 / 100 g, and more preferably of 100 cm, having an oil absorption 3/100 g, determined according to the Japanese standard JIS K 5,101th Calcined kaolin has proven particularly useful due to its high absorption capacity in the cavities.
  • an intermediate layer thus formed acts as a heat reflection layer, whereby the heat sensitivity of the recording material and thus the printing speed in the thermal printer can be increased. Further, such an intermediate layer can positively contribute to leveling of the substrate surface, thus reducing the amount of coating paint necessarily required to be applied to the heat-sensitive recording layer. Particularly advantageous is the formation of an intermediate layer with a basis weight in a range of 5 to 20 g / m 2 and even better between 7 and 10 g / m 2 .
  • the novel heat-sensitive recording sheet has a protective layer covering the recording layer of the second sheet-like material.
  • Protective layers bring about an increase in the resistance of the heat-sensitive recording layer to environmental influences such as water, plasticizers, which are used, for example, in insertion covers offered for receiving tickets, oils and fats.
  • the protective layer covering the recording layer is characterized by good printability.
  • a coating color as proposed in EP-B- 0909242 is suitable.
  • the protective layer combines high environmental resistance with recyclability and excellent printability in the wet offset process.
  • the protective layer is relatively inexpensive to manufacture and apply in one layer.
  • At least one further material web may be formed between the first and second web-like material, which in a preferred embodiment is a film, in particular a polyester or polyolefin film.
  • a dyed paper web a so-called inlay
  • Other materials may also be used as further material web to be formed between the first and second sheet-like material.
  • the materials of the further material web it is necessary for the materials of the further material web to be formed between the first and second sheet-like material to have sufficient light transmission.
  • the integration of magnetic or magnetizable pigments in the offers Substrate of the first and / or second sheet material as a security feature at.
  • such pigments may be in or on the at least one between the integrated first and second sheet material formed further material web or applied.
  • the new recording sheet are between the first and second sheet-like material metal strip as a security feature educated.
  • a transponder between the first and second web-shaped material possible. It is under a transponder in the context of this invention a chip used as a security feature to understand with circulating Copper wire as an antenna, which provides automatic and contactless identification of him carrying product allowed.
  • the heat-sensitive recording sheet of the present invention is mainly for Use as a ticket and especially designed as a ticket.
  • the watermark optionally allows in conjunction with the other security features clear authentication of the recording sheet according to the invention. If necessary, further allow the other security features used a proof of attempted counterfeiting on on the recording sheet according to the invention generated typefaces. By preventing shadow of the watermark in the recording layer an undisturbed image reproduction is possible, what especially in the presentation of barcodes is of the utmost importance.
  • ticket is an entry ticket and in particular a ticket or train ticket to understand the various means of public transport.
  • a web of wood-free paper with a basis weight of 90 g / m 2 is produced as the first web-shaped material.
  • the paper web has generated by means of Eisseur watermark.
